[0021] like Figures 1 to 2 As shown:

[0022] When two metal pipes are butt-jointed and fixed, they need to be fixed by inserting screws into the flanges. The two supporting members on the frame 1 are used to be inserted into the interior of the metal pipe to fix it and drive it to rotate. At the same time, the flanges at both ends of the pipe are respectively located in the two flange rust removal parts. A reduction motor 3 is fixed on the frame 1. The output shaft of the reduction motor 3 is fixedly connected to the bidirectional screw 11. The reduction motor 3 is started to drive the bidirectional screw 11 to rotate, thereby changing the spacing between the two flange rust removal parts, so that it can be suitable for metal pipes of different lengths. When the metal pipe rotates, the two flange rust removal parts remove rust on the two flanges on the pipe.

[0023] The hole cleaning parts arranged on the rust removal parts of the two flanges are used to remove rust and clean the screw holes on the flanges when the pipe fittings stop rotating. After the bolt hole at the lower end is processed, the pipe fittings are controlled to rotate a certain angle to process the next bolt hole, thereby removing rust on multiple bolt holes on the two flanges in turn.

[0024] like Figures 1 to 3 As shown:

[0025] A guide rod is provided in the middle of the frame 1, and the two adjustment frames 3 are both slidably connected to the guide rod. The two adjustment frames 3 are both provided with a scraper 35 and an outer scraper 36, which form a U-shape, so that the two flanges on the pipe fitting are directly located in the two U-shaped scrapers 35 and the outer scraper 36 after installation. The scraper 35 and the outer scraper 36 are in contact with the two end faces of the flange respectively, and the upper end of the scraper 35 is in contact with the circumferential surface of the pipe fitting. When the pipe fitting rotates, the scraping blades on the scraper 35 and the outer scraper 36 scrape off the rust on the two planes of the flange.

[0026] When the bidirectional screw 11 rotates, it drives the two adjustment frames 3 to slide toward or away from each other, thereby changing the distance between the scraper 35 and the outer scraper 36 on both sides, so that it can be suitable for pipes of different lengths.

[0027] like Figures 4 to 5 As shown:

[0028] The outer scraper 36 is arranged on the door frame 31, and the scraper 35 is provided with a through groove, through which the scraper 35 can slide horizontally on the door frame 31, and the inner side of the scraper 35 is provided with a guide groove 39, and the fork 34 passes through the guide groove 39 on the scraper 35 and is inserted into the door frame 31, and the fork 34 is rotatably connected to the short screw 33, and the short screw 33 is threadedly connected to the door frame 31. When the short screw 33 is rotated, the fork 34 is driven to move toward the direction close to the adjusting frame 3 or away from the adjusting frame 3, and then the fork 34 drives the scraper 35 to move toward the direction close to the adjusting frame 3 or away from the adjusting frame 3, thereby changing the distance between the scraper 35 and the outer scraper 36, so that it can be suitable for flanges of different thicknesses.

[0029] like Figure 5 As shown:

[0030] The flange rust removal part also includes a crossbeam 32, a long screw rod 37 and a socket 371. A through groove is also provided on the outer scraper 36. The outer scraper 36 can slide on the door frame 31 through the through groove. The door frame 31 is fixedly connected with a crossbeam 32. The vertical plate and the crossbeam 32 at the outer end of the door frame 31 are respectively fitted with the two end surfaces of the outer scraper 36, thereby limiting the horizontal sliding of the outer scraper 36, so that the outer scraper 36 can only slide vertically on the door frame 31, and then when the scraper 35 moves left and right, the distance between the scraper 35 and the outer scraper 36 can be changed;

[0031] Furthermore, when the flange is placed between the scraper 35 and the outer scraper 36, the circumferential surface of the flange contacts the scraper blade on the portal frame 31, so that the circumferential surface of the flange is derusted when the pipe rotates; the lower ends of the scraper 35 and the outer scraper 36 are connected by a socket 371, and a long screw rod 37 is threadedly connected to the socket 371. The long screw rod 37 is rotatably connected to the crossbeam 32. When the long screw rod 37 is rotated, the socket 371 can be driven to move up and down, thereby driving the scraper 35 and the outer scraper 36 to move up and down, thereby changing the length of the scraper 35 located at the upper end of the portal frame 31, so that flanges of different diameters can be placed in the portal frame 31, the scraper 35 and the outer scraper 36, and derusted;

[0032] On this basis, the lower end of the outer scraper 36 is connected to the socket 371, and the lower end of the scraper 35 is provided with a trapezoidal block, and the socket 371 is slidably connected to the trapezoidal block, so that when the socket 371 moves up and down, it can simultaneously drive the scraper 35 and the outer scraper 36 to move up and down synchronously, and the scraper 35 can slide horizontally on the socket 371, so it will not affect the change of the distance between the scraper 35 and the outer scraper 36.

[0033] like Figures 5 to 6 As shown:

[0034] The flange rust removal part also includes a short screw rod 38, which is threadedly connected to the socket 371. The short screw rod 38 is rotatably connected to the outer scraper 36, and the outer scraper 36 contacts the outer end surface of the flange to remove rust on the outer end surface. When the top ends of the scraper 35 and the outer scraper 36 are kept flush, the scraper 35 and the outer scraper 36 can remove rust on both side end surfaces of the entire flange. When the short screw rod 38 is rotated, the outer scraper 36 is driven to move upward, so that the upper end of the outer scraper 36 is higher than the upper end of the scraper 35. At this time, the outer scraper 36 contacts the outer end surface of the flange and can also contact the outer end surface of the pipe fitting. In this way, when the pipe fitting rotates, the outer scraper 36 can also simultaneously grind the outer end surface of the connection between the pipe fitting and the flange. The height difference between the upper ends of the scraper 35 and the outer scraper 36 is the thickness of the pipe wall, which makes the grinding more thorough.

[0035] like Figures 7 to 9 As shown:

[0036] The hole cleaning part includes a hollow arc scraper 4, a slide 41, a slider 42, an articulated arm 43, a top plate 44 and a rotating shaft 45. The slide 41 is installed on the inner end surface of the inner scraper 35. A hydraulic cylinder I is fixedly connected to the slide 41. The movable end of the hydraulic cylinder I is fixedly connected to the top plate 44. An articulated arm 43 is respectively articulated at the upper and lower ends of the top plate 44. The outer ends of the two articulated arms 43 are respectively articulated to the two sliders 42. The two sliders 42 are respectively slidably connected to the two ends of the slide 41. A motor 1 is fixedly connected to the top plate 44. The output shaft of the motor 1 is fixedly connected to the rotating shaft 45. Two arc scrapers 4 are symmetrically arranged on the rotating shaft 45.

[0037] When the two arc scrapers 4 correspond to the screw holes on the flange, the hydraulic cylinder I is started to retract and drive the top plate 44 to move toward the direction close to the flange, thereby driving the two arc scrapers 4 to be inserted into the screw holes. Once the motor is started, the two arc scrapers 4 are driven to rotate to grind and remove rust from the inner wall of the screw hole.

[0038] like Figures 9 to 10 As shown:

[0039] The hole cleaning part also includes a socket 46 and a square rod 47. Two sockets 46 are fixedly connected to the rotating shaft 45. The inner walls of the two arc-shaped scrapers 4 are fixedly connected to the two square rods 47. The two arc-shaped scrapers 4 are respectively slidably connected to the sockets 46 through the two square rods 47 thereon. The two arc-shaped scrapers 4 are centrally symmetrical with respect to the rotating shaft 45, so that the square rods 47 on the two arc-shaped scrapers 4 are staggered with each other and will not block each other; the two sockets 46 at the inner end are fixedly connected to the two hydraulic cylinders II, and the movable ends of the two hydraulic cylinders II are respectively fixedly connected to the two square rods 47 at the inner end;

[0040] When the two hydraulic cylinders II are started simultaneously to drive the two arc scrapers 4 to move closer to or away from each other, the distance between the two arc scrapers 4 can be changed, thereby being able to grind and remove rust from screw holes of different diameters.

[0041] like Figures 7 to 8 As shown:

[0042] The hole cleaning part further comprises a U-shaped frame 48, which is fixedly connected to the inner end surface of the inner scraper 35, and the slide 41 is vertically slidably connected in the U-shaped frame 48, and a hydraulic cylinder III is fixedly connected to the U-shaped frame 48, and the movable end of the hydraulic cylinder III is fixedly connected to the slide 41;

[0043] The hydraulic cylinder III is started to drive the slide 41 to slide up and down, thereby changing the position of the two arc scrapers 4 on the inner scraper 35, so that the screw holes on the flanges of different diameters can be polished and rust-removed, thereby realizing the polishing and rust-removal of the flanges on the entire pipe fitting.

[0044] like Fig.11 As shown:

[0045] A hardware parts processing device, further comprising an insert rod 2, a main scraper 21, a side scraper 22 and a bidirectional screw 23, wherein the insert rod 2 is vertically slidably connected to the middle part of a guide rod on a frame 1, a hydraulic cylinder IV is fixedly connected to the guide rod, a movable end of the hydraulic cylinder IV is fixedly connected to the insert rod 2, a main scraper 21 is fixedly connected to the upper end of the insert rod 2, a side scraper 22 is slidably connected to each of the two ends of the main scraper 21, a bidirectional screw 23 is rotatably connected to the insert rod 2, two side scrapers 22 are respectively threadedly connected to the two ends of the bidirectional screw 23, and the two side scrapers 22 are respectively in contact with the inner end surfaces of two inner scrapers 35;

[0046] The main scraper 21 contacts the circumferential end surface of the pipe fitting. When the pipe fitting rotates, the main scraper 21 scrapes off the rust on the circumferential surface of the pipe fitting. The main scraper 21 is driven up and down by controlling the hydraulic cylinder IV, so that the main scraper 21 can be applied to pipe fittings of different diameters.

[0047] The two side scrapers 22 extend the length of the main scraper 21. The two-way screw rod 23 is rotated to drive the two side scrapers 22 to slide closer to or away from each other, thereby changing the overall length of the main scraper 21 and the two side scrapers 22, so as to grind and remove rust from the outer wall of pipes of different lengths.

[0048] When the pipe rotates, the upper ends of the two inner scrapers 35 can also grind the outer wall of the pipe at the contact point with the pipe. The outer ends of the two side scrapers 22 are in contact with the two inner scrapers 35, so that the two inner scrapers 35 cooperate with the two side scrapers 22 and the main scraper 21 to achieve seamless connection, and the entire outer wall of the pipe can be grinded.

[0049] like Figures 11 to 12 As shown:
